November 2013 Replication Data Loss Issue

What is the November 2013 Replication Data Loss Issue?

This is an issue, discovered Nov. 18, 2013., which can cause data corruption on a Hot-Standby replica when it is (re-)started, by marking committed transactions as uncommitted. This issue is fixed in the December 5th 2013 update releases.

When will this be fixed?

The PostgreSQL project released an update release on December 5th which fixes this issue. We strongly advise all users who are using the builtin replication to apply that update.
A patch for the issue has been committed to the git branches of all affected versions.

What can I do to prevent this issue until then?

If you are currently using 9.2.4, 9.1.9 or 9.0.13 and use any form of builtin replication do not install the most recent update. Instead, wait for the next update (9.2.6, 9.1.11 and 9.0.15) to come out.

Options for users who have already updated, or are running 9.3, include:

if you are using 9.2.5, 9.1.10 or 9.0.14, downgrade your replica servers to the prior update release (9.2.4, 9.1.9 or 9.0.13).
